DBforBIX is a daemon designed to work in combination with Zabbix Enterprise Monitor to provide multi-tiered monitoring, performance, and availability reporting and measurement for the many kinds of different databases, along with server performance metrics. It provides an effective mechanism to acquire data from numerous databases installation, and in turn provides this information for monitoring and performance metrics to your Zabbix server. You can then utilize the reporting capabilities of Zabbix for all data collected, and provide analysis such as graphs and service level agreement metrics for stakeholders.
Geomajas caching plug-in is a plug-in for the Geomajas mapping framework that improves the speed by caching, by default based on the Infinispan cache library. The cached data can be tiles, features, bounds, or rasterized data (for the rasterizing plug-in). It has a configurable caching strategy, and automatically invalidates data when needed.
Immutable Collections for Java is a library providing immutable/persistent collection classes for Java. While collections are immutable, they provide methods for adding and removing values by creating new modified copies of themselves. Each copy shares almost all of its structure with other copies, to minimize memory consumption. The library includes a singly-linked (cons/cddr style) list/stack, an integer tree-based indexed list, a 2-3 tree-based random access indexed list, a 2-3 tree-based map, a hash tree-based map, and hash- and tree-based sets. All collections provide immutable Cursor as well as standard Iterator classes for looping through all elements. A utility class provides functional style algorithmic processing of Cursors, including foldLeft, foldRight, collect, select, and reject. The 2-3 tree and integer tree classes are optimized for performance and can be used alongside java.util Collections when immutability is needed for safe data sharing.
